Thanks for spreading the word, Steve. People need to learn this very easy and incredibly powerful “trick” for the early rails. I use it almost everywhere, unless I know ahead of time a network is going to be running multiple trains very soon (Like one I have with 4 passenger trains, 2 oil, 2 goods and 2 lumber trains all in close proximity of each other)
Specifically the game uses what OpenTTD refers to as Path signals. Only place signals where you want a train to make a stop, never anywhere else. You’ll need to set these at intervals to create “sections” that let trains behind start moving again. It’s quite simple once you grasp the basics. 🙂
